I-DoD 5220.22-M yinkqubo esekelwe kwisetyenziswe kwindlela yokuhlanjululwa kwedatha esetyenziswe kwiinkqubo ezahlukeneyo zefayile kunye neenkqubo zokubhubhisa idatha ukuze ibhale ngaphezulu ulwazi olukhoyo kwi- hard drive okanye kwenye idivayisi yokugcina.
Ukutshabalalisa i-hard drive usebenzisa indlela ye-DoD 5220.22-M yokuhlanjululwa kwedatha iya kuthintela zonke iindlela zokubuyisela iifayile ezisekelwe kwisofthiwe ukusuka ekuphakamiseni ulwazi kwi-drive kwaye kufuneka inqande ininzi ukuba ayinayo yonke indlela yokubuyisela i-hardware.
Indlela yeDoD 5220.22-M idla ngokungachanekanga njenge- DoD 5220.2-M (.2-M endaweni ye .22-M).
I-DoD 5220.22-M Indlela yokuSula
Indlela yokuhlanjululwa kwedatha ye-DoD 5220.22-Iqhele ukusetyenziswa ngendlela elandelayo:
- Ukupasa 1: Ubhala i-zero kwaye uqinisekise ukuba ubhala
- Ukupasa 2: Ubhala omnye aze aqinisekise ukubhala
- Ukupasa 3: Ubhala umlinganisi ongenanto kwaye uqinisekise ukubhala
Unakho ukufumana iintlobo ezahlukeneyo ze-DoD 5220.22-M kuquka iDD 5220.22-M (E), i-DoD 5220.22-M (ECE), okanye abanye. Ngamnye uya kusebenzisa umlingisi kunye nokuncoma kwayo (njengoko ku-1 kunye no-0) kunye neziganeko ezahlukeneyo zokuqinisekisa.
Ngona kunjalo, kuninzi enye inguqu yeDDD 5220.22-M ebhala i- 97 ngexesha lokudlula lokugqibela endaweni yomntu ongenanto.
Isofthiwe yeeFayili eSebenzisa i-DoD 5220.22-M Indlela yokuSula
Kukho iinkqubo ezininzi zamahhala ezinokukhetha ukusebenzisa i-DoD 5220.22-M yokulinganisa izinga lokucoca ukucima yonke ingcaciso kwi-drive drive.
Isixhobo sam ukususa idatha yedatha yokuthanda idatha esisebenzayo esisebenzisa i-DoD 5220.22-M, phakathi kwezinye iindlela, yi- DBAN , kodwa abanye bambalwa banokukhetha, kunye ne- CBL Data Shredder .
Njengoko ufunda ngasentla, ezinye iinkqubo zefayile ezitshintshayo ezisebenza kwiifayile enye okanye ngaphezulu ezikhethiweyo endaweni ye-drive yonke, kwakhona zisebenzisa i-DoD 5220.22-M.
Imizekelo yabanye abafake iifayile zefayile ezikhululekile ezinokukhetha kwi-DoD 5220.22-M esekelwe kwifayile yokucoca iquka i- Eraser , iFree File Freder , kunye ne- Freeraser .
Okunye malunga neDDD 5220.22-M
Indlela yokuhlanjululwa kwe-DoD 5220.22-M yayichazwe okokuqala yi-US National Security Programme Programme (NISP) kwiNational Manufacturing Programming Manual (NISPOM), ekhoyo apha (le PDF ), kwaye enye yeyona ndlela ichanekileyo esetyenziswe kwiprosoft software yokubhubhisa.
Uninzi lweenkqubo zokubhubhisa idatha luxhasa iindlela ezahlukeneyo zokucocwa kwedatha ngokubhekiselele kwiDoD 5220.22-M, njenge- Erase Ekhuselekileyo , Ukubhala iZero , iData yeDatha kunye neSchneier .
Qaphela: I-NISPOM ayichazi nayiphi na imilinganiselo karhulumente wase-US yokucocwa kwedatha. I-Cognizant Authority Authority (CSA) ijongene nemigangatho yokuhlanjululwa kwedatha.
Njengoko ndiyiqonda, indlela yeDoD 5220.22-M ayisavunyelwe (kwaye akukho nanye iprogram esekelwe kwisicwangciso sokuhlanjululwa kwedatha) ekusebenziseni ngamalungu amaninzi e-CSA kuquka neSebe lezoKhuseleko, iSebe leMandla, iKhomishoni yoLawulo lweNyukliya, kwaye kwiCentral Intelligence Agency.
Ngaba i-DoD 5220.22-M ilungileyo kunezinye iindlela?
Mhlawumbi ayinandaba nantoni na into ebalulekileyo idatha indlela oyisebenzisayo. Ekubeni uninzi lwethu osusa i-drive yethu enzima senza njalo ngaphambi kokuba sithengise idrayivu okanye sifake i- OS entsha, akufanele kube yinkxalabo enjalo malunga nokuba zingaphi izilwanyana ezingenanto zibhalwa kwi-drive ngokubhekiselele kwizinto okanye zeros .
Ngaphezulu, uninzi lwabantu abazama ukufumana idatha kwi-drive eyithengiweyo yithenda mhlawumbi basebenzisa izixhobo zemihla ngemihla njengeRecuva , kwaye ngelixa bezama ukutyhila idatha esusiweyo, abayenzi kakuhle xa idatha isula indlela.
Nangona kunjalo, xa ukhetha indlela yokuhlanjululwa kwedata, unokucinga ukuba kuya kuthatha ixesha elingakanani ukusula i-drive. Ukuba unesidanga esinzima kakhulu, Bhala iZero kuza kuthatha ixesha elincinci lokugqiba ngaphezu kweDDD 5220.22-M, okuya kukhawuleza kunokugqithisa kunokufana ne- Gutmann enokuthi isebenze ngaphaya kwama-30.
Kwakhona qwalasela ukuba ngaba ukuqinisekiswa kwenziwa emva kokupasa. Ekubeni ezinye zeekhompyutha zingenza i-DoD 5220.22-M iphumelele ngendlela eqinisekisa ukuba ngamnye ubhale ekupheleni kwipasiphi nganye, yonke inkqubo iya kuthatha ixesha elide kunokuba isebenzise indlela eyahlukileyo yokusula engaqinisekisiyo konke (njengeKhusekileyo okuKhuselekileyo) okanye lilinde kude kube sekupheleni kokudlula kokugqibela ukuqinisekisa ukuba idatha ibhalwe ngaphezulu.
Enye into enokuthi ibone indlela oyisebenzisayo yile data echanekileyo esetyenziselwa ukubhala ngaphezulu i-drive drive. Ezinye zisula iindlela, njenge-Bhala Zero, sebenzisa kuphela i-zero esikhundleni seendawo ezingenanto. Kungenzeka ukuba ukusebenzisa izalathisi ezingaqhelekanga kwenza kube lula ukuba idatha ingabuyiselwa.
